How the mighty NFL running back position has fallen

WE'VE ALL HEARD the narrative -- how after a decades long drift toward becoming a pass-first (and pass-second and pass-third) league, the NFL now values running backs about as much as it does Gatorade coolers. (Although, in the league's defense, some of those coolers can hold up to 10 gallons.) But is it true?
